Graffiti on public benches is a common urban eyesore. Removing it effectively without harming the bench's protective finish requires a careful, methodical approach. The best method often depends on the bench's material and the graffiti's medium.
Start with the gentlest option: warm, soapy water and a soft-bristled brush. For stubborn marks, specialized graffiti remover gels or citrus-based solvents are highly effective. Apply the product, let it dwell as directed, and agitate with a non-abrasive pad before rinsing thoroughly with low-pressure water.
For painted metal or concrete benches, low-pressure power washing (under 1200 PSI) can be successful if kept at a safe distance to avoid etching the surface. Always test any cleaning method on a small, inconspicuous area first.
Prevention is key. Applying a clear, anti-graffiti coating after cleaning creates a protective barrier, making future removal much simpler. This proactive step saves time and preserves your benches' appearance for the long term.
